Question no power to mobo after windows install

I have recently built a brand new pc with the following parts:
I9-14900kf
msi gaming trio 5060ti 16gb
2x32gb vengeance ram
NZXT N7 Z790 motherboard

i had the system running and loading bios, went through the windows install as normal and then got a DRAM issue during boot.

i reseated the ram with the system powered off and now have no power to motherboard at all.

i have tested my psu and that is working and giving the right readings on the right pins of the 24pin mobo connector

i have had a refund on the mobo and the PSU so have bought replacements but i am slightly worried that these may not have been the underlying issue. Can anyone help me shed some light on this?

TIA

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model, if the unit is recycled from an older build.

i reseated the ram with the system powered off and now have no power to motherboard at all.
Rams populating slots A2 and B2 on the motherboard, per your motherboard manual; page 25?

Mind sharing how you tested the PSU? Using the paperclip method? if so, that's a flawed test. It doesn't tell you how much power the PSU can effectively output.

Moved thread from Motherboards section to Systems section.

The ram was in the A2 and B2 slots on the motherboard! it was tested with a multimeter and the paperclip test yes!

i'm not completely brand new to building pc's just had a long time out!
